Elevated Blood Lead Levels??

Hi Ladies.  Does anyone have experience with an elevated Blood Lead Level in their little ones?? Eliza's first blood lead level result - via a capillary draw (finger prick) - came back elevated and of course now I'm worried The doc said she'll need to have a venous blood draw (from her arm) to get an accurate reading, because the capillary draws can give falsely high readings. The poor thing - having to have a venous blood draw at only 2!! I wonder how that will go.

Anyone have any advice? I'm sort of freaking out... I know kids who live in the city have higher levels due to the urban environment, but the "normal" range is 0-5 and Eliza's came back at 13.8.  

P.S. Don't google "lead poisoning in toddlers".  UGH!
